IMPROVEMENT IN DIES FOP SHAPING BOOT AND SHOE COUNTERS.

Specification forming part of Letters Patent No. 222%83, dated December2, 1879; application filed January. 6, 1879.

To all whom it may concern:

Be it known that I, JOSEPH KIEFFER, of Montreal, in the Province ofQuebec and Dominion of Canada, have invented certain new and usefulImprovements in Dies and Formers for Shaping Heel Counters or Stiifenersfor Boots and Shoes, of which the following, taken in connection withthe accompanying drawin gs, is a specification.

My present invention is an improvement upon the invention described inLetters Patent No. 205,191, granted to me June 25, 1878, for machine formolding heel-counters, and relates to the construction of the mold orfemale die and the former, whereby the counter is more perfectly shaped;and it consists in the combination of a reciprocating male die or former-having its front or operating end shaped to correspond to the desiredinner contour of the counter or stiffener, and a female die or moldhaving a parallel-sided entrance, a back concaved to fit the convex endof the former, and movable central side sections provided upon theirinner sides with concaved. moldingsnrfaces, and each adapted to bepartially rotated about an axis of motion perpendicular to the plane ofmovement of the reciprocating former by the movements of said former,and thereby curve inward the forward ends of the counter and cause themto assume,

ing-surfaces, two movable side sections placed in said openings in themain die-pieces, and having formed in their inner sides curvedmolding-surfaces, each adapted to be partially rotated about anindependent axis of motion,

and a back piece provided with a curved innor surface to fit the convexend of the former, as will be further described.

It further consists in a sectional female die or mold for shapingcounters in which the main sides and back or end piece yield slightly,

moving in straight, or nearly straight, lines, and the central sidesections have imparted to them a reciprocating rotary motion aboutindependent axes of motion.

it further consists in a sectional female die or mold provided with sidemolding surfaces or shapers, adapted to be partially rotated aboutindependent axes of motion located forsections in the positions whichthey assume when the male former has completed its forward motion. Fig.6 is a vertical transverse section on line z 2 on Fig. 5 and Figs; 7, 8,and 9 are, respectively, a plan, elevatiom'and end view of the male dieor former.

In my previous patent heretofore cited the female die or mold was madein two parts, F F, placed side by side within a box or casing composedof adj ustable plates g, g, and I, held in position by bolts and wedges,with "sheets or plates of rubber or other elastic material placedbetween said female die and its'inclosing-casing, and the male formerwas a straight plunger having a rounded end, as shown and described insaid patent. as near as may be, the desired shape of the Theconstruction of the mold and former there described worked admirably;but there was one objectionable feature connected there with, which wasthe fact that the machine left the two sides of the counter toostraight, such sides being substantially parallel with each other asviewed in plan, when in' fact a properly-shaped counter requires tobe'narrower' between the two sides at their extreme forward ends than ata point nearer the extreme rear of the counter.

'To obviate this objection and produce a counter by means of areciprocating former and a female die or mold that shall beshaped toconform to the shape of the last npon'which the shoe is to be built isthe object of my present invention; and as my improvements are limitedto the construction of the former and the female die or mold which areto be used in place of the former and mold shown and described in thebefore-mentionedLetters Patent I have not thought it necessary to showor describe the other working parts of the machine.

In the drawings, A A are the two main portions of the female die ormold, but containing only a small portion of the molding or shapingsurface, and that at or near the entrance or month, where the said partsA A are each provided with a shoulder, a, and curved recess b, to aid inthe proper doubling under of the blank to form the bottom lip or flange,as described in my former patent.

The sides a of the entrance to the mold are made straight and parallelwith each other longitudinally for some little distance, though curvedtoward each other vertically, which straight surface, by its adhesion tothe blank as it is forced into the mold by the male die or former B,(shown in Figs. 7,8, and 9,) causes said blank to be drawn tightlyaround the curved end of the former B.

. The side pieces, A A, are both cut away at their rear ends for agreater part of their height, and into the space so formed is fitted theback piece, (3, having its inner face concaved to fit the convex end ofthe former B, the object of this back piece being to do away with ajoint in the extreme rear of the mold, which I have found in practice tobe objectionable on account of the formation upon the rear of thecounter of a ridge caused by forcing the material into said joint.

Each of the side pieces, A A, also has cut through its side a mortise,into which is fitted the semi-cylindrical side piece, D, having formedin its inner or cylindrical side a concave recess, 01, shaped to fit theside of the curved working-head e of the male former B, said side piece,D, being so formed and mounted in the skeleton side piece, A, that itmay be partially rotated about an axis of motion by the forward motionof the former B, and may thus press the counter-blank around theinwardly-curved portion of the former-head e, which enters the moldlast, and thus complete the shaping of the counter, and then it may bemoved in the opposite direction around its axis as the former iswithdrawn.

The former B is provided with a shank, f, by which it is secured inposition in the reciprocating plunger of the machine, and has formed onits opposite end the head e, before referred to, shaped to correspond tothe desired contour to be given to the counter, as shown in Figs. 7, 8,and 9.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is-- 1. The combination of a male die or former having acurved or rounded end and sides curved vertically and longitudinally, asset forth, and a sectional female die or mold, the

entrance of which is straight, or nearly so,

longitudinally, and having a back or rear end surface concaved to fitthe convex end of the male die or former, and provided with central.

side sections concaved upon their inner sides to fit the curved sides ofthe former-head, and adapted to be partially rotated about an axis ofmotion perpendicular to the plane of movement of the former,substantially as and for the purposes described.

2. The combination of the male die or former B, provided with curvesided and convexended head a, and a sectional female die or moldcomposed of the main side pieces, A A, provided with thelongitudinally-straight surfaces c, the central movable side sections, DD, and the back piece, G, all arranged and adapted to operatesubstantially as and for the purposes described.

3. A female die or mold for shaping shoecounters, composed of the mainside pieces, A A, having openings cut through their sides, and providedat or near the entrance or mouth thereof with longitudinally-straightsurfaces 0, shoulders at, and curved recess or cutaway I), the centralmovable side sections, D D, and separate back piece, 0, all constructedand arranged relative to each other substantially as described.

4. A die or mold for shaping shoe-counters in which the main sides andback yield only slightly in straight, or nearly straight, lines, and thecentral side sections have imparted thereto a reciprocating rotary orvibratory motion about independent axes of motion, substantially asdescribed.

5. In a female die or mold for shaping shoecounters, two side molding orshaping surfaces adapted to be partially rotated about independent axesof motion located forward of the back or rear end of the mold,substantially as described.

6. In an apparatus for molding boot and shoe counters, the combination,with a male die or follower, of a female die having a concave heel-blockand wings or side pieces, each adapted to be moved about a fixedvertical axis of motion, substantially as set forth.

7. In an apparatus for molding or shaping boot and shoe counters, thecombination of a reciprocating male die or former, a concave heel-block,and wings or side pieces forming a continuation of the heel-block, andadapted to be vibrated about a fixed vertical axis of motion,substantially as and for the purposes described.

Executed at Montreal, Province of Quebec, this 26th day of December, A.D. 1878.
